Thank you for your comment Jerry. I wholly agree that if there's a technique that gets you out of writing endless lists, then you should take advantage. As the difficulty ramps up though, there sometimes isn't much choice. If you have a screen grab or photo of the puzzle at the particular point you want me to look at, and put it into a Google Docs, that might work.

I got to a place with nowhere to go, so I "logic-ed" that the 1-8 in the center cell of the top middlebox must be a ONE because the 1-8 and the 2-8 directly below (bottom row of top middlebox) it could not both be 8. This was NOT logical but seems it was lucky because I finished from there. Perhaps you could suggest where I could have gone from there. Thanks for responding and helping.

See 2:57 - this explains why those two cells have to be 1 and 5. Think of it this way: If those 2 cells were 6 and 9, where would the 1 and 5 go in that row?

@@caryg1069 Yeah you are write, I missed that. Thanks... :)

I haven't played this in a while, but there is a great tutorial by Simon Smith here on TH-cam if you wanna check it out!

Hi Julie - the reason it cannot go into column 2 is because of the upper-left 3 X 3 box - all 3 cells in column 1 are already filled in that box, so the 1 can only go in column 2 within that box. Stated another way: if a 1 was placed in R9C2, then there would be nowhere within column 1 that could take a '1'.

Thank you for the encouraging comments, Stephen. I apologize that I haven't been publishing any more videos recently. I certainly want to keep this project going, but the current format has proven VERY labor-intensive for the strategies that require "lists". Hope to be able to offer some new content soon.

Hi Vinod, could you direct me to a specific time stamp that you found challenging?

Wait, let me watch it again.

The main reason for my confusion is, that you wrote pair candidates in only one cell. So rather than watching puzzle, i need to listen your speech which i can hardly follow without a subtitle. Due to the fact that English is not my native language, i always rely on visuals rather than speech.

That's fair. I admit that I use notes differently than many others. I cover this in lesson 4, but in short: those notes aren't all of your choices. They show which row or column a number will fall under within its 3X3 box. e.g. At 1:45, the 2 cells in the green box will be {3,7} in some order. These #'s are in a column that needs a {3, 4, 5, 7, 8}. Skip to 2:40: this therefore means the 3 cells in the lowest box must be {4, 5, 8}, in some order.

No sheet music; done by ear. The chord progressions don't change a lot throughout the song so it isn't too bad to piece it together.
